FRANCIS H. RICHARDS, OF HARTFORD, CONNECTICUT, ASSIGNOR, BY MESNEASSIGNMENTS, TO AMERICAN TYPOGRAPHIO CORPORATION, A CORPORATION OF NEWJERSEY.

MANUFACTURE OF TYPE AND TYPE-BARS.

Application filed December 1, 1902, Serial No. 133,383.

To all whom it may concern:

Be it known that I, FRANoIs H. RICHARDS, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inManufacture of Types and Type-Bars, of which the following is aspecification.

This invention relates to means for manufacturing die-made characters,such for instance as types, by the aid of heat from,an extraneous sourcewhich serves to reduce the internal cohesion of the material of theblank and thereby facilitate the dieforming of the character.

In the practical application of the present invention. to themanufacture of a logotype or line of type, the heat from the extraneoussource is applied to the successive portions of the blank upon which thedies or like instrumentalities, when properly selected and located,operate to form a desired succession of types.

The source of heat will usually be a stream of heated fluid, such asheated air or a gas flame, and in the practical operation of a mechanismfor manufacturing a succession of types in accordance with the presentim provements, the heating agent is directly ap plied to the portion ofthe blank located at the working point and upon which the (lie next tooperate comes into contact; in point of time the heat is appliedimmediately prior to the operation of the die.

To more freely permit the carrying out of the die treatment or operationthe means for heating the type-blank portion may be drawn backward outof the way just before the die operation begins, and in order thatthedie and the mechanism associated therewith for its operation shall bethe more eifectually protected from the heat used for heating the lank,suitable guard-like devices will ordinarily be employed for shieldingthem. These devices are preferably of such construction and organizationas to confine the application of the heating agent to the comparativelysmall portion of the edge of the blank with which the die next operatingis to engage.

A further feature of the present invention relates to thecross-sectional conformation or contour of the type-forming edge of theblank. This will preferably be somewhat tapering for the reason that byemploying a blank whose side faces converge toward each Specification ofLetters Patent.

other, presenting a relatively narrow face to the dies, the type-formingportion of the blank, that is, the portion from which the type lines andbodies are made is raised to the necessary and proper temperature morequickly than the lower and wider portions of the blank in which acomparatively great degree of rigidity should be preserved during thetype-making operation to eflectuallyresistthe crushing down tendenciesof the manipulations to which the material is subjected by the dies.

In the drawings which accompany the present specification there is setforth a mechanism organized to make a succession of types (a logotype orline of type) and using a stream of heated fluid directed in successionagainst successive type-forming portions of the edge of the blank.

In these drawings, Figure 1 is a side elevation of such a mechanism,certain portions of the supporting frame upon which the various parts ofthe mechanism are mounted being removed to more clearly show parts lyingbeyond. Fig. 2 is a plan view, the die carrier and the swing frame uponwhich it is mounted being removed in this figure. Fig. 3 is a verticalsection on the plane of the line 83 in Fig. 1. Fig. 4 is an elevation ofa portion of the main or driving shaft illustrating a pair of camsmounted thereon which cams are effective to feed the die and blankagainst each other in forming the type and to cause the approach andrecession of the nozzle for the heated air toward and from the blank inthe blank holder of the machine. Fig. 5 is an end elevation of the partsset forth in Fig. 4. Figs. 6 and 7 are views of the cams indicated inFigs. 4 and 5. Fig. 8 is partly an elevation and partly a sectionillustrating the manner in which the forming rolls act u on the edgeportion of the blank to cause t e side faces of the latter at andadjacent to its extreme upper or type forming edge to converge towardeach other. Fig. 9 is a plan view of the parts set forth in Fig. 8. Fig.10 is a perspective view showing the relation of the delivery nozzle tothe edge of the blank which is established during the operation of themachine and immediately prior to the making of a type, this figure alsoillustrating a guard employed for the purpose of confining the action ofthe heating agent to that portion of the blank with which the die nextoperating is to come into contact. Figs. 11,

12 and 13 are sectional views, the plane of each section being disposedin line with the axis of the die and transversely of the blank in theblank holder, these several views indicating the relation of the blankto dies adapted for making different types after such dies have beenwithdrawn from contact with the types made by them on the blank. Fig. 14is a sectional view of a die, the blank and the aforesaid guard, andillustrates the parts in the position taken by them immediately beforethe making of the type by the selected die and while the portion of theblank under the die is being heated. Fig. 15 is a sectional view of theparts in the position indicated in Fi 14, the section of the plane beingat rig t angles to that yielding the latter figure. Fig. 16 is a viewsimilar to Fig. 14, but in this figure the guard and the delivery nozzlefor the stream of heated fluid are assumed to have been withdrawn andthe die to have descended and completed the making of the type; and Fig.17 is a sectional view corresponding to Fig. 15 but representing theparts in the position they have assumed in Fig 16.

Similar characters of reference designate corresponding parts in allfigures.

The articular organization of mechanism which Fhave adopted in thepresent instance for illustrating an application of my present inventionis one in which a plurality of se lective dies are capable of beingbrought one after another in a desired succession to the working ointand when a die is there located the blanl f may be forced against thedie to form on the blank a type. Thereafter the die may be withdrawnfrom en agement with the blank and the latter shifted lengthwise of itssupporting guide or holder to bring the next type-making portion of theedge of the blank to the working point.

The application of the present invention is not restricted to anyparticular construction of parts or to any particular species of type ortypebar-making mechanism in which t pes, typebars or logotypes are madetirough the instrumentality of dies which serve to impress the edge ofthe blank. Referring however to the particular mechanism set forth inthe drawings attached to the present specification, the same issupported u on a base or bed B which may be supported by legs such as b.The holder for the blank is designated by 2 and the same is se cured tothe base or bed B and. is provided with a slot 2 whose sides sustain theblank against the operation of the dies; through this slot the blank maybe shifted or fed ste -by-step by means that will be adverted to ater.

An appropriate number of dies will be employed depending upon the usesto which the machine is applied. In the present instance but acomparatively small number of these dies are indicated and the same aredesignated without preference by D. For convenienee in the selection andadjustment of a determinate die to the working point of the machinethese dies may be supported on a carrier, which latter is in thisinstance in the nature of a die wheel 3, whose shaft 4 is journaled inthe hub 5 of an arm 5. In the particular organization herein disclosedthe feed ing of a selected die and the blank together results from afeed movement of the die carrier which movement is conveniently effectedby making the aforesaid arm 5 a swing arm and ournaling the same upon apin such as 6 extending between. uprights such as 7, '7

erected upon the base plate B. j

A spring pressed locking pin 8 is shown for securely holding the diecarrier in an adjusted posi tion; this pin is mounted in an arm 8extending from the hub 5 and can be inserted in any one of a number ofopenings 8 in the die carrier and in co-ordinate relation with the diesthereon.

S is the main or driving shaft of the machine, and the same is in thisinstance j ournaled in bearings s, 5' supported by correspondingbrackets 9 extending downward from the lower surface of the base plateB. It is during the rotation of this shaft that the various operationsinvolved in making a type are performed, and in the simple character ofmechanism illustrated in the drawings, a crank handle 9 is indicated asa means for rotating the shaft.

The to-and-fro movement of the die carrier 3 involved in the approach ofa located die toward the blank, the feed of such die into the edgethereof and the recession of the carrier until it regains its normalposition is effected from the driving shaft S in this instance through.the instrumentality of a cam such as IOseeured to the shaft and havingthe proper contour to give the proper move ments to the swing arm 5through an intermediate connection which in the form thereof illustratedcomprises a link 11 pivoted at one end to the free end of the arm 5 andcarrying a cam roll 12 adapted to bear against the periphery of the cam10. This link 11 is in this instance slotted, see the slot 11, toembrace the shaft S and be guided thereby, and the cam roll 12 is causedto firmly press against the periphery of the cam 10 through the tensionof a spring 13 secured at one end to an arm 14 working in a slot Z) inthe base B and depending from the hub portion 5 of the arm 5 surroundingthe pin 6, and at the other end to the arm of a bracket 14: secured tothe lower surface of the base plate B. Some means suitable for thepurpose will be employed for shifting the blank, such as (whether thesame be in short lengths or in ribbon form) through the slot 2 of theblank holder. In the particular form of such feed device illustrated thesame consists of a feed screw 15 whose operating shaft 15 is journaledin bearings 16, 16 in such position as to adapt the teeth of the feedscrew to engage with the side face of the blank. A thumb wheel 17 on theshaft 15 of the feed screw is indicative of a means for manipulating thelatter and shifting the blank forward stepby-step.

Referring now in detail to means for heating the blank and which heatingconstitutes an important feature of the present invention, it may bestated in a general way that the invention includes means for heatingthe type-forming edge of the blank, analogous in its mode of operationwith respect to its effecting a succession of distinct and successiveheat applications to the intermittent working of the (lies along theedge of the blank like the application of the dies, the heat applied tosuccessive type-forming portions of the edge of the blank. The mechanismthrough Whose operation such applications of the heating agent is madeis so organized and timed, however, as to cause the heating of any oneortion of the blank to take place immediate y before the proper diecomes into engagement with such portion.

In the particular way in which the various elements are herein combinedand related, and since, furthermore, guard devices are preferablyemployed for protecting the types already formed as well as the diemechanism from the action of the heat, these guard devices wouldnaturally when in proper position for affording such protection,interfere with the operation of making a type. The means for causing theimpingement of the stream of heated air or gas, or the flame against theedge of the blank and also the guards for protecting the partsenumerated are therefore given a reciprocatory movement toward and awayfrom the edge of the blank. Under these conditions, when the guards anddischarge nozzle are in their innermost position, (during which time thedie carrier is withdrawn and the die thereon is wholly disengaged fromthe blank) the next portion of the blank to be subjected to the actionof a die is being heated. When the temperature of such portion shallhave been raised a sufficient amount, the parts are caused to recede totheir furthermost backward position and the blank is then free to havethe die operate upon it.

In the particular embodiment of the invention herein disclosed, theblank is heated by a gas flame which burns at a nozzle 18, gasfedthrough a delivery pipe 18 mounted to reciprocate in uprights 19, 19,erected on an auxiliary bed-piece 19 attached to the base plate B. Aflexible gas supply conduit such as 20 is attached to the end ofdelivery pipe 18, and in this instance the gas flame is a burner flamethe nozzle 18 being somewhat smaller than the encircling delivery pipeand air passing in through perforations 18" to.

mix with the gas issuing from the orifice 18'. The inner end of the pipe18 is, in the construction of guard illustrated, suitably formed toconstitute such guard or shield 22 adapted when the flame, etc., isimpinging against the portion of the blank at the working point, toconfine the heat to the blank and prevent the same from beingcommunicatod to the die immediately above it. I prefer, moreover, thatthis shield shall be so formed as to protect the completed types at therear; for this purpose the shield has in this instance adownwardly-extending lip 22 adapted to enter the space separating thetype last made from the portion of the edge of the blank immediately inadvance.

The simple means indicated for effecting the reciprocatory motion, asaforesaid, of the shield and the leading-in or supply pipe 18 isoperated from the main driving shaft S, and comprises in the formthereof shown a rock arm 23 pivoted intermediate its endsby a pivot pin24 to a lug 25 depending from the lower surface of the base plate B.Adjacent to its lower end this rock arm carries an antifriction or camroll 26 adapted to bear against the surface of a cam 27 mounted 011 themain shaft S contact between the two is assured by a spring 28. At itsupper end the rock lever 23 is bifurcated and the side arms 23 slotted,see the slots 23, to embrace trunnions 29 extending from a collar 29fixed to the tubular member or pipe 18. The cam 27 is so formed and itsoperation is so related to the operation of the cam 10 as to produce thetimed reciprocation of the shield and leading-in pipe already referredto.

I may combine with the heating device means for more or less fullyshutting off the flow of heated air during such time as the leading-inpipe is withdrawn from close proximity to the blank. Such regulation ofthe flow of the heating agent may be effected automatically through theoperation of a suitable valve, such as 30, in the supply pipe 18, thearm 31 of which valve is connected by a link 82 with a relatively fixedpoint; this latter may be made adjustable for the purpose of regulatingthe extent to which the flow is first opened and then shut off. Asillustrated herein the link 82 is connected with an adjustable screw 33passing through a threaded opening in one of the uprights 19.

A further particular feature of the present invention and which isdesigned more especially to localize the heat in those portions of theblank more immediately concerned in the making of the successive typestowit: the edge of the blank. To effect such result, the edge ispreferably of a relatively smaller cross-section than the portion of theblank below, and the rigidity of which is concerned in supporting theforming type during the subjection of the metal thereof to the treatmentof the die. By making the extreme upper edge of the blank somewhatnarrower than the main body of the blank that is by beveling or taperingthe upper portion of the blank, the edge is brought to a temperaturesufficient to decrease the cohesion of the metal more quickly than themain body of the blank and thus the forming operation of the working dieis assisted. As regards the extent to which the upper portion of theblank is tapered as the same appears in cross section, this will begoverned by the relative widths, crosswise of the blank, of the typeswhich are to be formed and such width will ordinarily be such ascorresponds approximately to the width of the narrowest charac- 1 ter ortype to be made, thus requiring the lateral flow of the metal in the diein the making of characters or types of greater widths.

The blank may be presented to the machine with the upper portions of itsside faces beveled, or I may so mount forming rolls, such as 34, 34,upon the machine as to compel the successive portions of the blank to beforced between them some time before such portions reach the workingpoint. These rolls are mounted, in the construction shown, upon bosses35, 35 of the blank holder 2 and are of such form and are placed such adistance apart as to cause the beveling of the upper edge w of the blankto the desired amount.

, A mechanism such as has been hereinbefore described operatessubstantially in the following manner: Assuming the die carrier 3 tohave been adjusted so as to bring the desired die to the working pointand to be locked in this position by the locking pin, the crank 9 maythereupon be turned. Prior to the time in which the cam 10 comes intocontact with the cam roll 12 to force the latter down and hence feed thedie against the blank, the leading-in pipe 18 will have projected thegas flame against that portion of the blank under the located die. Asthe crank 9 is turned the cam 27 retreats from the antifriction roll 26permitting the spring 28 to withdraw the leading-in pipe and the shields22, 22, and shut off the gas supply following which the die carrier ismoved downward and the die forced into the blank by the cam 10. Furthermovement of the shaft S results in the retreat of the die and thereengagement of the cam 27 with the anti-fricti0n roll 26. Theleading-in pipe 18 new advances and the valve 30 is operated to furtheropen the passage through such pipe and permit the full flame to play onthe edge of the blank. The feed screw 17 may in the meantime be adjustedto shift the formed type such as t (designated without preference) andbring the next portion of the blank to the working point, durin whichshifting movement the forming rol s 34, 34 operate to bevel the edge ofthe blank and give to the same a tapering form.

A repetition of the o erations and movements ust described su ces toroduce a desired succession of types along t e edge of the blank, whileword separating spaces may be made by a space formin die analogous inoperation to the type ma ing dies.
